Talk about taking matters into your own hands. Many people are told that they shouldn’t crack their knuckles and that doing so isn’t just bad matters – but bad for you. But is this really true? And does knuckle cracking lead to arthritis?
Donald Unger from California set out to find the answer on his own. He began cracking the knuckles on his left hand at least twice a day – while never cracking those on his right hand. He did so to create a long term study of knuckle cracking (we aren’t even making this up). After sixty years, he had still not developed arthritis. He actually published his findings in the journal of Arthritis and Rheumatism and talked with the LA Times about his experiment.
Cracking your knuckles can cause ligament or soft tissue damage, worn researchers. A study that was published in the Annals of Rheumatic Diseases linked hand-cracking to hand swelling and lower grip strength. However, it does not appear to be the danger that some parents warn their children it will be.
